The Boise Fly Fishing Expo is Jan 14-15 this year, at the Expo Idaho (not the hotel where it used to be). Should be a good event with demonstration fly tiers, good lecture programs, a casting pond, and enough vendors to keep you busy for a day (and inside, where it will be nice and warm).

I'm already dreaming about getting out of my heavy insulated waders and back into some proper breathable waders come springtime...
